[单项选择]Inventory
Inventory belongs to an important element of the cost of doing business in a large company. If a company is assembling cars, they must have a large number of parts in hand so that the assembly line does not stop because one part is missing. If cars are going down the assembly line and one person is supposed to fasten wheels on to the car, the whole line will stop if he runs out of fasteners. This means that several hundred men will be waiting while someone must find fasteners for the wheel. So there must be a sufficient number of parts of all sorts nearby in order to keep the car assembly line running smoothly.
A large supply of spare parts is very expensive, so a company will try to keep its inventory as low as it can without finding it necessary to stop production for lack of a part.
In a planned company, i.t was often difficult to secure spare parts and so many companies ordered many extra parts and kept large supplies of parts so that if a mistake was made

Fuel

the efficiency of their newest aircraft, the 787 and A350 respectively. Their
clever designs and lightweight composites certainly make a difference. But a
group of researchers at Stanford University, led by Ilan Kroo, has suggested
that airlines could take a more naturalistic approach to cutting jet-fuel use,
and it would not require them to buy new aircraft.
The
answer, says Dr Kroo, lies with birds. Since 1914, scientists have known that
